What is image watermarking?
Image watermarking is the process of overlaying text, a logo, or a pattern onto a photo to assert ownership, prevent unauthorized reuse, or brand your content. Watermarks can be visible (semi-transparent text or logos) or invisible (embedded metadata). Trndinn's watermark tool adds visible watermarks entirely in your browser — no server upload, no signup.
Professional photographers, e-commerce sellers, and content creators use watermarks to protect intellectual property. According to the Copyright Alliance, over 2.5 billion images are stolen online daily [Copyright Alliance, 2024]. A visible watermark deters casual theft while keeping your work shareable.
Frequently asked questions
How do I add a watermark to a photo for free?
Upload your photo to Trndinn's Watermark tool, type your watermark text (or upload a logo), adjust font, size, color, opacity, and position, then click Download. Everything runs in your browser — free, no signup.
Can I use my own logo as a watermark?
Yes. Switch to the "Image / Logo" tab, upload your PNG logo (transparent background recommended), and position it anywhere on the image with adjustable opacity and size.
What is tile watermarking?
Tile watermarking repeats the watermark text or logo across the entire image in a grid pattern. This makes it much harder to crop out, providing stronger protection for high-value photos.
